WebNov 25, 2014 · 3. The hex () function does not pad numbers with leading zeros, because Python integers are unbounded. C# integers have a fixed size (64 bits in this case), so have an upper bound and can therefor be padded out. This doesn't mean those extra padding zeros carry any meaning; the integer value is the same.

Python Bitwise Shifts – Real Python

WebThe bits are whole 1 or 0 - you can't shift by a part of a bit thus if the number you're multiplying by is does not factor a whole value of N ie. since: 17 = 16 + 1 thus: 17 = 2^4 + 1 therefore: x * 17 = (x * 16) + x in other words 17 x's thus to multiply by 17 you have to do a 4 bit shift to the left, and then add the original number again: WebBit masking in Python.
